Thanks for the reply.
I'm very tempted. The bike had a brembo radial mc when I got it, and I liked it when it worked Never really got to the bottom of what was wrong with it, I think it was leaking through one of the seals. At the moment I have a brembo MC from a Monster, which is probably quite similar to the stock item, and it's ok, but I'm thinking an upgrade would be good (the monster item looks bad too, it's kind of a bronze colour).
I'm very tempted with the ISR.

Was the clucth lever a simple swap? Does it use the same cables as the standard?
